Embodiment 1

[0035] In Embodiment 1, two multi-axis rotor remote control aircraft 1 powered by external three-phase AC power supply form an aerial formation. The aircraft 1 includes a fuselage 2 , an electric rotor 19 , a flight state computer control system, a radio signal receiving, processing, and transmitting facility, an aircraft load, and a remote controller 4 . A group of three transmission lines 6 forming a loop with the external power supply 5 and the electrical load of the aircraft is adopted. The proximal end of one end of the transmission line 6 is electrically connected to the aircraft 1, the other end of the transmission line 6 is connected to an automatic winding device 7, and is electrically connected to the external power supply 5 through the automatic winding device 7; the external power supply 5 passes through the transmission line 6 Continuously supply the aircraft 1 with electrical energy.

Embodiment 2

[0042] In Embodiment 2, the three-terminal double-plug automatic connector includes two sockets 16 , two plugs 17 and two automatic plug lockers 18 . The plug 17 has a concentric three-wire structure and is electrically connected to the power line 6 . For the specific content of the concentric three-wire structure, reference may be made to the prior art including the double-core plug of the mobile phone earphone. The spring 21 is slidably fitted on the transmission line 6 . The automatic plug locker 18 includes a resisting block 22 and an electric depressing tongue 23, and adopts a signal connection or an electrical connection with the flight status computer control system. The automatic plug locker 18 is normally closed, that is, the electric tongue 23 stretches out and presses the plug 17 on the block 22 to lock the plug 17; at this time, the spring 21 is in a compressed state. The socket 17 is also electrically connected to the power line 6 .

Embodiment 3

[0046] In Embodiment 3, two multi-axis rotor remote control aircraft 1 powered by external power supply are connected in series with the automatic winding device 7 on the ground through a common set of power lines 6 and take power from the external power supply 5 . The automatic winding device 7 includes an electric reel 24 and two bases 25 connected with the electric reel 24 . And inside the aircraft 1 above, an automatic winding device 29 is also provided, including an electric reel 24 . It is used to retract the power line 6 located below. This series connection mode and the arrangement of power lines help the aircraft above to fly higher and more freely because the aircraft below bears a large part of the weight of the power lines.

[0047] The single aircraft adopts the automatic winding device 29, which is suitable for flying close to the ground without dragging the power line, which can avoid or greatly reduce the wear and tear of the power line and the fetters, and ca...

Abstract

A multi-axis aircraft powered by an AC power supply uses a multi-axis aircraft asynchronous motor parallel speed regulation method. The multi-axis aircraft is characterized by comprising an aircraft body, multiple electric rotor wings, an aircraft load, a flight state computer control system, a remote controller, and an AC power supply. The flight state computer control system comprises a satellite positioning terminal and a communication module. The three-phase windings of each motor are connected in series to form three branches. Each branch is connected with the power supply in series or in parallel. At least one winding or a part of the winding of each motor is connected with a multifunctional module in parallel and each branch at least comprises one multifunctional module. The states of the motors are changed by a change in the states of the multifunctional modules. The multi-axis aircraft powered by external three-phase AC power may decrease the weight of multiple batteries in virtue of an external power facility and has a long-time air flying capability.

Description

technical field [0001] The invention relates to a multi-axis aircraft asynchronous motor parallel speed regulation method and products. Background technique [0002] Existing multi-axis aircraft adopt multi-axis rotor symmetrical arrangement. When the initial state is hovering, the rotation speed of one of the or adjacent 2 to 3 rotors is appropriately slowed down and the total lift remains unchanged. Due to the slowing down of the rotor The corresponding reduction of the lift force causes the axis line of the aircraft to tilt, so that the wind force of each rotor generates a horizontal component to push the aircraft to move horizontally in the direction of the position of the slowed rotor. Most of the existing multicopters are powered by batteries, and the air-stay time is relatively short in relation to the capacity of the batteries. In view of the advantages of asynchronous motors and our proposal to use an external power supply for wired power supply, it is necessary to...
